DYNAMIC VALUE MECHANISM FOR COMPUTER STORAGE CONTAINER MANAGER ENABLING ACCESS OF OBJECTS BY MULTIPLE APPLICATION PROGRAMS

Computer apparatus stores a subject value and a chain of sequentially associated value handlers for the subject value. The chain includes a top value handler and a bottom value handler, each of the value handlers in the chain except the bottom value handler invoking the respective next value handler when invoked, the bottom value handler performing an operation on the subject value when invoked. The value operations can be data read operations, data write operations, etc., and the value handlers in the chain can perform data transformations and/or data redirections, transparently to its caller.
